Lee I will have to agree with you on the sound wave matter. It WILL losen Parts Just like the harmonics that seem to plague our Inlines. At one time When My headers were not of equal lenght and the collecter Ended right along side my tranny(& bell housing area) Things came lose Like shifter, some linkage to name a few and All had lock washers or some type of locktight. Once I tuned everything Meaning tube lenght and collectors I never once had this issue again. And cliffords headers Are Far from being of Equal length. And as for who sells what headers any more I'm not realy sure, Because i build my own headers Now It's cheaper at half the cost And I know they are of equal lenght. And I mit add much easier to install around the linkage now as well and a little more ground clearance Then what cliffords long tubes are for the chevy2s( seeing that I smashed my tubes the first nite out with them On a manhole cover) they said I needed 14in. tire which I had. But they just sat to low under the draglink and I hit the first tube In the first set of 3 that pass under the draglink.So that is what prompt me into learning how to build headers.Plus i wanted a equal tubes. Hope this helps }[oooooo]
